An autothrottle system to be interfaced with a full-authority digital engine control (FADEC) system having a command input that receives sensed power-control input (PCL) position signaling indicative of a manual throttle setting for an aircraft. The autothrottle system generates automated power command signaling that is synthesized to virtualize electrical characteristics of the sensed PCL position signaling such that the automated power command signaling is recognized by the FADEC system as sensed PCL position signaling.

The invention relates to a control system for an internal combustion engine incorporating an engine shut-off valve for permitting or preventing air flow to an engine, and in particular a diesel or gas-fueled engine. The control system comprises a valve controller unit including a receiver capable of receiving incoming signals from a plurality of sources, and processing a received incoming signal to generate an output signal to output a shutdown command for actuating the shut-off valve for preventing air flow to the engine, and recording, in a memory, event data including a source identifier of the received incoming signal resulting in output of the shutdown command signal.

A method for the operation of a vehicle drive-train of a working machine having a drive motor, a transmission whose transmission ratio can be varied continuously, and a drive output. A rotational speed (nmot) of the drive motor can be varied by the driver, by the driver's actuation of a first control element (50), within a rotational speed range (53) delimited by an upper characteristic line (nmoto) and a lower characteristic line (nmotu). The characteristic lines (nmoto, nmotu) are functions of a reciprocal transmission ratio (irez) of the transmission. Furthermore, the rotational speed (nmot1) of the drive motor that can be set by the driver by way of the first control element (50), can be influenced by the driver's actuation of a second control element (51) and as a function of an operating condition of the working machine.

A method for controlling a marine internal combustion engine includes operating the engine in a lean-burn mode, wherein a first fuel/air equivalence ratio of an air/fuel mixture in a combustion chamber of the engine is less than 1. The method includes comparing a change in operator demand to a delta demand deadband; comparing a speed of the engine to an engine speed deadband; and comparing a throttle position setpoint to a throttle position threshold. The method also includes immediately disabling the lean-burn mode in response to: (a) the change in operator demand being outside the delta demand deadband, and (b) at least one of: (i) the engine speed being outside the engine speed deadband, and (ii) the throttle position setpoint exceeding the throttle position threshold. The engine thereafter operates according to a set of mapped parameter values configured to achieve a second fuel/air equivalence ratio of at least 1.

A control device for an internal combustion engine includes a throttle valve opening degree detector, an air bypass valve controller, and a torque reduction controller. The throttle valve opening degree detector detects an opening degree of a throttle valve which is provided downstream with respect to a compressor of a supercharger. The air bypass valve controller opens an air bypass valve based on a reduction change in the opening degree of the detected throttle valve. The air bypass valve is configured to open and close a bypass path. The torque reduction controller controls the throttle valve to reduce the opening degree of the throttle valve while an automatic transmission connected to the internal combustion engine is in an acceleration shifting in order to execute a torque reduction control. The air bypass valve controller maintains the air bypass valve in a close state during the torque reduction control.

A speed limiting device may include a communicator configured to communicate with a tire air pressure monitor, a steering angle detector, a yaw rate detector and an engine controller of a vehicle; a storage configured to store limited speed information corresponding to slip information, in a form of a table; and a controller configured to acquire slip information based on a steering angle detected by the steering angle detector and a yaw rate detected by the yaw rate detector when abnormality information is received from the tire air pressure monitor, to check a limited speed corresponding to the acquired slip information, and to output the checked limited speed to the engine controller.

A vehicle control system to operate a vehicle autonomously with improved energy efficiency and ride quality is provided. A controller is configured to set a limit value of an operating point of an engine to reduce noises and vibrations. The operating point of the engine is restricted by the limit value within an acceptable region where an engine speed is higher than the limit value but an engine torque is lower than the limit value. The limit value is set to a first limit value when the vehicle is operated autonomously while carrying the passenger, and to a second limit value to expand the acceptable region when the vehicle is operated autonomously without carrying the passenger.

Embodiments of the present invention provide a method and system for enacting various driving profiles based on identifying the age and gender of the user. Initially, identifying information is acquired from a user of a vehicle. An identification program determines whether the driver is known, by comparing the identifying information to a set of stored identifying information. If the driver of the vehicle is known, as the identifying information from the user is similar to stored identifying information, then a specific driver profile associated with the specific driver is activated. If the driver is not known, as the identifying information from the user of the vehicle is not similar to the stored identifying information, then the age and gender of the user of the vehicle is determined. Based on the determined age and gender of the driver of the vehicle, various vehicle setting ranges are enacted.

A control method is provided for controlling an internal combustion engine for a vehicle configured to engage a lockup clutch during a fuel cut, and to decrease a lockup hydraulic pressure at a fuel cut recovery to bring the lockup clutch to a slip engagement. The control method includes estimating a torque of the internal combustion engine generated by the fuel cut recovery when a fuel cut recovery condition is satisfied. The control method further includes decreasing a decrease amount of the lockup hydraulic pressure as the torque is greater.

A supplemental fuel system includes a fuel mixer. The fuel mixer includes a nozzle and a stem. The nozzle is configured to be positioned within a conduit of an air supply system for a compression-ignition engine. The nozzle has a body defining a first inlet positioned at a first nozzle end thereof, an outlet positioned at a second nozzle end thereof, a second inlet positioned between the first nozzle end and the second nozzle end, and a nozzle passage extending from the first nozzle end to the second nozzle end that is configured to receive air flowing through the conduit. The stem has a first stem end interfacing with the second inlet. The stem is configured to extend through a wall of the conduit such that a second stem end is positioned outside of the conduit.
